The effect of concomitant hysterectomy on complications following pelvic organ prolapse surgery

Purpose: Pelvic organ prolapse (POP) surgery is performed with and without concomitant hysterectomy depending on a variety of factors. The objective was to compare 30-day major complications following POP surgery with and without concomitant hysterectomy. Methods: This was a retrospective cohort study using the National Surgical Quality Improvement Program (NSQIP) multicenter database to compare 30-day complications using Current Procedural Terminology (CPT) codes for POP with or without concomitant hysterectomy. Patients were grouped by procedure: Vaginal prolapse repair (VAGINAL), minimally invasive sacrocolpopexy (MISC), and open abdominal sacrocolpopexy (OASC). 30-day postoperative complications and other relevant data were evaluated in patients who underwent concomitant hysterectomy compared to those who did not. Multivariable logistic regression models assessed the association of concomitant hysterectomy on 30-day major complications stratified by surgical approach. Results: 60,201 women undergoing POP surgery comprised our cohort. Within 30 days of surgery, there were 1722 major complications in 1432 patients (2.4%). Prolapse surgery alone had a significantly lower overall complication rate than with concomitant hysterectomy (1.95% vs 2.81%; p <.001). Multivariable analysis revealed odds of complications following POP surgery was higher among women who underwent concomitant hysterectomy compared to those who did not have hysterectomy in VAGINAL (OR 1.53, 95% CI 1.36–1.72), OASC (OR 2.70, 95% CI 1.69–4.33), and overall (OR 1.46, 95% CI 1.31–1.62), but not in MISC (OR 0.99, 95% CI 0.67–1.46.) Conclusion: Concomitant hysterectomy at the time of pelvic organ prolapse (POP) surgery increases the risk of 30-day postoperative complications in comparison to prolapse surgery alone in our overall cohort.
